Clolarion was an ancient Purifier, based on the template of the brain scan of ExecutorClolarion, considered to be one of the greatest protoss warriors. The purifier retained the rank of executor, and lead the purifiers in the Purifier Rebellion, fighting against its Conclave masters. The Clolarion purifier was sealed in Cybros along with the rest of the purifiers.
In 2506, during the End War, the Daelaam under the command of HierarchArtanis came to Cybros to reactivate the purifiers. Clolarion once again acted as their spokesman and leader during the mission, and ordered the Purifiers to engage the zerg on the station, and then purified the surface of Endion, the forest moon Cybros orbited.
With the battle over, Artanis asked the purifiers to join the Daelaam in the war against Amon. Clolarion questioned his sincerity and how the purifiers would be treated, but agreed to consult with the other purifier commanders. They accepted the offer and joined forces with the Daelaam.

Clolarion later fought alongside Talandar, housing his consciousness within a Purifier carrier.
"We prefer to keep to ourselves. While we trust the word of Artanis that we will not be slaves again, there is little crossover between our societies. We have different needs. No reason for our paths to cross, beyond when one might ask a favor of us in the effort of reconstruction."
After the Daelaam reclaimed Aiur, Clolarion and the Purifiers remained loyal to Artanis, aiding in the reconstruction of the planet when they were called upon, but he and the majority of the Purifiers largely kept themselves in self-isolation in their network. When Talandar was investigating a series of mysterious deaths, Clolarion stated that due to their isolation, the Purifiers had little knowledge of their biotic kin.
Clolarion appears in Co-op Missions as a hero fielded by Fenix. He possesses the ability to inhabit Fenix's carriers. It is equipped with a solar beam weapon, which allows it to increase in damage the longer it stays on a single target. If Clolarion's carrier is destroyed, he will instantly inhabit a nearby carrier. Clolarion's carrier is able to build interdictors that can drop area of effect bombs, as well as an anti-air auto attack.
